Application le nnovember 12, 1921, Serial No. 514,521. Renewed March 31, 1924.

This invention relatesl to ges producers,

and has for its chief object to improve the etiiciency and operation of the producers. More particuieriy it is 'the eim oi the inven.- tion ifo provide certuin improvements esili@- cialiy in the relation of the lower :32h sul)- port and shell or body oi' the producer, and in the control of the movements' of these perils and of certain pertsfmoveble therewith so es to obtain a. niore/eieetive sheL ring or grinding of' the ashes/in the eeh none, and a more eirlective wey of preventing the formation of'blow holesrin the ashes.

Additionally tlm" invention rentes to o novel construction which I have provided. so as to producto e tearing and shearing action in the ashes 1noth aeove and below interally extending blast ernis.

in another aspect the invention rela-tes to certuin novel structurel arrangements in wiring the supporting oi' the producer body ash pau so that they may rotate toher or independentiy of each other aboutJ e common :isis but with the pan supported wholly independently' of the producer body so that any slight irregularity in the setting or movement of one peri; will have no effect;

on the other part.

The invention 'may be further briefly suninuirized as consisting in certain novel details oi`- Construction, and zombi ions and arrangements of perte .i ich i di be described in the specification and pointed out iu the appended claims. 4.

Referring now to the drawings, l0 represents the shell or body ot the producer, the shell being rotatable, and in this instance being suppi'irted on rollers 1l mounted ou stationery columns l2 arranged about the producer body, hose rollers being engaged by u laterally projecting liunge or track 13 secured to the producer body.

At the top is the producer body cover,` indieeted at le, he seme being connected te the top the producer body through the medium or r. 1vater seal i5, and 'being stutionerily supported on the columns l2. On the top or cover lei will be mounted such auxiliery apparatus :is the. feed mechanism which in iiig. 2 is indicated generally by the reicrenee. character 16, vand 'th poker n'ieelianisin. the top oi which is shown at l'i' in Fig. 2. However, these parts do not directly enter into or form a part ottheypresent invention. hence they are not and need not be shoivu in detail.

CII

an ssh pan Lliuto which a flange or skirt revenir upper and lower enrV form o? a sleeve 31 which is capabie of ro-` tating in the upper central. part ofthe blast hood.. bviouely With this arrangement the hood 'and spider will 'rotate together when the ash` pan and. producer body rotate together, and the hood and spider will have a relative rotation when the ash pan and producer body are relatively rotated.

As shown in Figs. l and Li the blast arms simply entend out'to the producer body, and the blast is delivered into the ash zone through the major portion of the straight sections of the arms. lt may be desirable, however, that the arms be provided with lateral blast nelivery extensions adjacent the shell or body o the producer, as shown in Figs. 1l and 13. lin Fig. 11 the blast Aarms are designated 25E, with arc shaped delivery extension 25, and in 13 Wherein the blast arms are designated 25 the outer portions of the arms are provided with straight inwardly directed delivery extensions 25g. lt will be understood that the airwill pass outwardly along the arms 25 and 25t and laterally along the delivery 'extensions, and that the arms and extensions are both provided preferably at the bottom with openings for the delivery of the air ,into the ash zone.

y When the arms are provided with lateral extensions such as shown in Figs. il and 13, the lower sides of the extensions are pretf erably rovided. with a saw tooth 'forni indicated 1n Figs. 12 and 14 by the reference character 251 in which event the openings for the delivery of air are located immediately behind the shoulders formed by the teeth so that as the extensions of the arms -cut or slide through the ashes there will be inore or less clear spaces behind the teeth 'for the outiow of air. The chief fund tion ot the tapered teeth on the lower sides ot the arm extensions is to' force the ashes downward when the pan is stationary and the arms are forced through the ashes. For

the same reason the lower sides ot the armsy lie-further modiiied by having the arms coniinunicate with and deliver air into an annular blast ring carried by the producer body substantially as shown in my prior application, Serial No. 268,293, filed lecember 26. 1918.

Takingaip next that important feature of my invention'which brings about a. shearing Y and twisting,r ot' the ashes iii the lower part of the `producer body or between the produc-er body and the ash pan, it was heretoa tore stated that the producer body and ash pan are at times rotated. together and at intervals are caused to rotate relatively. ln causing the producer body and ash pan to rotate together it is preferable that one of these parts only be positively' driven, and that the'other part be rotated by `friction created by the body of ashes extending between the producer body and ash pan. As tar as my invention in its broadest aspects is concerned, it is immaterial whether the producer body or pan is positively driven, but l prefer that the positive driving means be applied to the producer body and that it be positively and continuously rotated, and that the ash pan be rotated by the friction of the ashes atnthe same speed as theproducer body, except when the parts are designed to be relatively rotated. 'llo produce the relative rotation I provideJ means whereby at intervals preferably for a fraction or" each revolution the part which is not positively driven be held stationary and then released so 4as to again move forwardly at the speed of the positively driven part. lThe mechanism for accomplishing these results will now be described.

On one of the stationary columns 12 a motor 33 is provided, (see particularly Fig. 2) which through the mechanism here shown, is preferably utilized to cause the rotation of the' producer body and ash pan, except at intervals when the latter is held ,stationary by a part of the mechanism to be described, and `also preferably operates the mechanical feed mechanism which may be provided on the cover of the producer to feed the :Enel thereto, and the poker which may likewise be supported by the cover to swing or oscillate. `.Islovveveiy as far as the present invention concerned, it is immaterial whether the described mechanism performs all of these functions, and therefore the mechanism may be other than 4here. shown.

In the specic mechanism shown-,fthe inotor 33 is coupled to a shaft 3st which, through yvorm and worm wheel gea-ring 35v enclosed 1n a housing 36, rotates a ,vertical spuit 37 which, through Worin and Worm wheel gearn ing' 38, drives a horizontal shaft 39 which is ina plane above and at right angles to the motor shaft and shaft 34. This shaft 539 is provided at its inner end with a gear 4() adapted to continuously rotate the producer body at the desired 'slow speed, this gl'ear 40 engaging an annular rack 41 carried by the producer body, and in this instance formed on the top of the annular track lfl which lsts and travels on the supportingrollers lt will be observed by 4reference to Figs. 2 and 3, that at the top of the vertical shaft 37 Yis e cranlrhaving a rotating oicenter 'ashes in the plane ot' the arms and beneath tating the producer body causing the aN1 the blast hood is held stations-fry,v and hence notariat between the ashes and these parte including' acting automatically and at definite inter the blast arms and hood, but when the rotavals to hold the friction, driven part against tion ol" the ash pan is stopped, inasmuch rotation.
